Requirements for importing app into Appflow

Appflow
1

I plan to import an existing React Js project into Appflow.

Is there any condition for imporing an app?
( e.g Project structure, Build Script,…)

Thanks in advance.

Most React projects will build just fine. There are some exceptions like monorepos where you may need to make some tweaks (see here) but those are simple to set up.
